Fridgeswitch has an inbuilt electronic movement and vibration sensor which switches the 12 volt circuit of the caravan’s 3 way fridge ‘on’ when the vehicle is moving and turns the fridge ‘off’ when the vehicle stops.

Fridgeswitch has a varying timing circuit which may keep the fridge turned on for up to 3 minutes after the vehicle has stopped. This is to keep the fridge turned on while you are stopped at traffic lights.
